I feel like people who say this haven't seen KDE in a very long time. On a thinkpad it not only "just works", it works flawlessly, never demands attention without justification (i.e. no ads or superfluous items in notifications), every bit of hardware works, all the special keys, fingerprint reader and it's all recognized and usable and configurable from KDE.
Is there any particular distro you're using KDE on for this to work flawlessly on a Thinkpad? I have a Carbon Gen 6 on Windows 10 but one day will need to migrate. The device itself is sound and reliable.
